- W2383447319 abstract "This paper proposes a new meaningful robust digital watermarking algorithm based on second-generation Bandelet transform.Second-generation Bandelet transform is a novel multiscale geometric analysis method,which can adaptively trace the geometrical regular surfaces.This paper reduces the amount of computation and improves the transform speed by ameliorating the geometric angle direction search methods.According to HVS (Human Visual System) properties that human eyes are not sensitive to the change of image's textures and edges,the meaningful binary watermark information is embedded into the larger transform coefficients which describe these characteristics by odd-even quantization algorithm.The experimental results demonstrate that the proposed algorithm is not only invisible,but also robust to many attacks such as JPEG compression,superimposed noise,filtering and scaling attack etc." @default.
